I encounter my stepbrother masturbating and choose to soothe him by straddling his erect penis

When I stumbled upon my stepbrother pleasuring himself, I decided to take control. I seductively straddled him, my small, firm tits grazing his face. My petite, brown-skinned body moved rhythmically as I took him deep inside. Our passionate encounter was a mix of lustful kisses and intense fucking, culminating in a messy climax on my round, inviting ass.
